Considering Complexity

I hated it in CSC165, and I still hate it here. I understand that the time complexity of an algorithm is one of the most important things in computer science for obvious reasons, but I still have trouble with it. In any case, I've been reading my old CSC165 notes over and over again and ditto the course notes, along with a lot of poring over the relevant parts of the course notes. I'll have this in hand eventually, and if not, well at least it seems to be much less a focus of the course than in CSC165.
